AIR-COOLING APPARATUS.-

SPECIFICATION forming part of Letters Patent No. 248,732, dated October 25, 1881. Application filed August 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALFRED O. GARRAT'I, l\I. D., of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Air-Ooolin g Apparatus, of which the following is a specification.

In the accompanying drawings, Figure l is a side elevation of my improvement, part be ing broken away. Fig. 2 is a sectional elevation of the same, taken through the line 00 :0, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a convenient portable air-cooliu g apparatus.

The invention consists in an air-cooling apparatus constructed of a portable ice-vessel, a fan-blower, and a pipe to discharge the cold air, whereby the air will be thoroughly cooled before being discharged.

The invention further consists in the combination, with the ice-vessel, of a trough and spout to receive and discharge the water con-, densed upon the outer surface of the said vessel, and also in the combination, with the icevessel and fan-blower, of an extension-section, also having ice-rack, whereby thef'air will be thoroughly cooled before being discharged, and will be forced out in a strong current, as will be hereinafter fully described.

In the drawings, A represents a vessel of any desired or convenient shape and size, and which may be made of any suitable material, except the bottom, which should always be made of wood or other non-conductor of heat.

B is a rack to receive ice, which rack is placed upon, or is supported from, or at a little distance above, the bottom of the vessel A. The vessel A is open at the top to allow air to enter to be cooled.

In the side of the vessel A, below the rack B, are formed one or more openings, which have collars O secured in them. The collars G are provided with caps D, so that the discharge of cold air can be controlled as may be required, and so that a pipe or pipes, E, can be placed upon: one or morefof the said collars C to direct the current of cold air to any desired place.

Around ithe lower part of the vessel A is formed a trough, F, to receive the water condensed upon the outer surface of the said vessel A and discharge it through a spout, G, into a receiving vessel placed beneath the said spoutG. In an opening in the side of the vessel A, at the upper surface of the bottom of the said vessel, is secured a faucet, H, through which the drip-water can be allowed to escape as it is formed, or can be drawn off at intervals. I prefer to locate the faucet H within or directly above the spout G, so that the same vessel can receive the water of condensation from the trough F and the drip-water from the melting ice.

In using the cooler the vessel A can be placed upon a table or bureau, or be otherwise supported above the person to be cooled,

so that the cold air from the discharge-openings in the vessel A will flow directly upon the person to be cooled; or pipes E can be applied to the collars O to direct the cold air to any desired part of the body of the said person.

In case a greater coldness be required than will be produced by the natural circulation of air, a small fan-blower, I, can be used, the easing of which is attached to a cover, J, fitted to the top of the vessel A, and through an opening in which the said fan-blowerI discharges its blast.

To the end of the fan-shaft of the blower I is attached a small pulley, K, around which passes a belt, L. The belt L also passes around a largerpulley,M, pivoted to the casing of the fan-blower I, and to a bracket or other support, N, attached to the cover J.

To the outerjournal of the pulley M is attached the crank O, by means of which the said :t'an-blower I is operated. When the fanblower I is to be used the height of the cooler can be increased by interposing a section, P, open at top and bottom, between the vessel A and the cover J. The section P is provided with a rack, Q, to receive ice, so that ice can be placed upon the rack Q to cool the air as it enters the section P, and other ice upon the rack- B to give the air an additional coldness before it escapes from the vessel A.

The pipe or pipes E can be made of any desired length and curved in any desired manner or made straight. With this construction, by the use of a fan-blower, the current A, open at the top and provided with the of cold air can be discharged in the upper capped collars G in openings thereof, with a to part of aroom, even when the apparatus is fan-blower arranged over said top opening, as

placed upon or near the floor. shown and described.
